Hi
im running a java mutithreaded application, its small server it can handle aroung 200 clients.but after reaching 60-70cliemts .this clients r applets .server going to ideal or it will crash after one to two hour.i am giving aroung 730mb for that application.in the same machine Tomcat is running. If anybody knows more abt this prblm .Help me
most of the Exception im catching and displaying in the console, this server application have a GUI window.that will vanish suddenly out printing any exception in the console.once we restarted it will work.but after some 3-4 hr it will become ideal or crashes.
this server is connected to a some other c process thorugh port. lots of threads are running inside the server.everthing inside the try-catch.if there is small no of clients connetc to the server thn this server will work fine.

Thank you for repeating the rambling of your original post. Do you plan on showing us any code or any stacktraces at any point?

}// switch( iReqType )
}// if( SanityCheck() )
}
}// try
catch( Exception e )
{
e.printStackTrace();
}// catch()
}// method AcceptClient()
this is the code to accept new client. this will calld in side
public voidrun()
{
while( true )
{
try
{
AcceptClient( oServerSocket.accept() );
}
catch( Exception e )
{
System.out.println(e);
//OMMisc.OMlog( "Run ( AcceptClient ) " + e.toString() );
}// catch()
}// while( true ) loop
}// method run()
now im running this application as Java Hotspot server VM.from today morning to till now no crashing.previosly it was running as normal application.that can give any changes(avoind crashes).
with regards
